Answer

Histologic demonstration of both endometrial glands and stroma in biopsy specimens obtained from outside the uterine cavity is required to make the diagnosis of endometriosis. Occasionally, the finding of fibrosis in combination with hemosiderin-laden macrophages is sufficient for a presumptive diagnosis.
